I would like to have a mechanism by which users can check their mental health regularly themselves through a series of standardised tests. This would be very useful for someone with hereditary mental illness and would like to keep a tap on their mental health.
There are numerous occasions by which someone may be at the risk of mental illness apart from hereditary reasons e.g. environment, age, side-effect from infections of implants, accidents, medication etc.
An easily accessible system with which a user can track the progress of their mental health would bring more awareness towards mental health and its treatment. A fitbit for mental health?
